[Bug] 360° images converted into overlapping cube images are not detected, even using exhaustive matching

[Bardo-Konrad]

Describe the bug
When converting 360 panorama images to cube-images with overlap using

aliceVision_utils_split360Images.exe -i input -o output --equirectangularNbSplits 8 --equirectangularSplitResolution 768

(aliceVision_utils_split360Images is part of the meshroom package)

and using them in colmap with exhaustive feature matching, I get around 2% of the number of pictures in the input folder in the images folder and a distorted result.

Environment:

• OS: Windows 10
• COLMAP Version 3.9.1-dev
• Capture Device 360 camera
